Saturday i added a few(8) community fish from the local feeders supply. Just to go ahead and pour in the DR Tims One and Only since its nearing expiration. Been doing fine until a little bit ago. I lost one of them. Noticed it kind of twisting around in the water going upside down. Turned off the powerhead to calm the tank down. He wasnt going around all crazy anymore but it did parish. The rest of them are doing fine. Not sure what happened but this is kind of the reason i got these first instead of just getting bass. Parameters are fine so it could have been stress or something. Only causes i can think of is being stressed for some reason, getting to close to the powerhead, or getting burned by the heater. Though the powerhead isnt really powerful enough to hurt them. Ive seen them be pushed away by it before. The heaters have one of the canister filters blowing right on them so i dont think they really could have been burned being i have quite a bit of current moving over then constantly. The pleco likes to suck on the heater sometimes. Not sure.
